Suitable for absolutely all OBD1 ECU brains with the option to chip external memory.

For $250 you can upgrade the old S300 V2 to a modern version.

The Hondata S300 has been modified from year to year, it is now a complete device in board form, with mask, heatsinks, and signal LEDs. The Hondata S300 is both a data logger (again, cut J12), a memory emulator, and a USB cable-controlled device. It is controlled, monitored, and tuned via the USB bus, which makes it very convenient to configure. In fact, Hondata S300 is an emulator of memory EEPROM 29C256, by means of what can be programmed and configure the machine on the fly, that is on the course of the car. It is installed inside the ECU, connects as to the brain's datalog (CN2), and most importantly, it is connected instead of the external memory chip. The best known Hondata system is the Hondata S300 or Hondata S300J. The engine's bogeyman, the Hondata S300, has all the functionality in one board It was not very popular, hence it was discontinued. On the chip that goes with the S200, comes a memory chip configured by Hondata with datalog, extended fuel map and ignition map. As a matter of fact, S200 is bloated S100 with additional functions like RS232 control, G-Sensor, and a couple of output functions. The firmware itself with maps will have to be edited through RomEditor 3 or 4, but about it a little later. The kit includes the device itself with a connector to the ECU brain datalog (CN2), respectively J12 jumper must also be removed. It is the device and its outputs and inputs can be configured for some sensors. The RS232 port can be used to interface and configure the unit with a laptop computer. It is possible to install the G-Sensor G100, which allows you to measure the acceleration of the car. The next product is the Hondata S200, fitted outside the ECU itself, discontinued in early 2008. Hondata S200 connected to datalog connector CN2 The firmware itself will have to be edited via RomEditor 3 or 4. Paying 200 dollars for 29C256 firmware and TTL termination board is not right, price of this product is about 10-20 Dollar, but there is always a choice. Of course to monitor the car parameters you will have to unsolder the J12 jumper, remove its diode or jumper, depends on the type of ECU brain. The S100 board itself is a TTL->USB conversion (CN2). If I understand correctly, it is a simple chip with software that adds a journaling function (datalog), extended ignition maps and fuel maps. Included, chip kit with chip and S100 board itself. Extended ignition and supercharger fuel maps.Setting up fuel cards, and ignition cards.And the first electronic product that Hondata makes is the S100, priced at about $200. The entire Hondata S100, S200, S300 series range is oriented towards the OBD1 ECU.
